How to rotate a watch collection
Wear the automatic that's closest to stopping, wind the hand-wound ones on a fixed schedule, and let the rest stop without guilt. That's a rotation that works for three watches or thirty.
Why rotate at all?
A watch you love but never wear is a watch in a box. Rotating spreads the pleasure around and matches watches to your day, and it keeps you from going back to the same one every morning by habit. The only real cost is keeping track of which watch is running and which has stopped.
Three rotation styles
By power reserve
Each morning, wear the running automatic that will stop soonest. It gets recharged, and the others hold their reserve a little longer. With three or four automatics that have 70 hours or more, you can keep all of them running without a winder.
By schedule
One watch per weekday, or one per week. It's predictable and makes sure everything gets worn, but it ignores reserve, so expect to reset watches often.
By occasion
A diver for weekends, a dress watch for evenings, a field watch for travel. It's the most natural but also the most uneven; some watches stop for months.
Most collectors blend them: a daily favourite, occasion watches when the day calls for them, and reserve deciding the rest.
Hand-wound watches need their own schedule
Hand-winders don't charge on the wrist. They need winding every day you wear them, and they stop after their reserve if you don't. Pick a routine: wind all running hand-winders together each morning, or only keep one or two running at a time.
Reserve decides how easy it is
| Reserve | Off the wrist | Rotation |
|---|---|---|
| 38 to 42 hours | Stops overnight on the second day | Hard to keep several running |
| 50 to 60 hours | About two days | Works with two or three watches |
| 70 to 80 hours | A full weekend | Easy with three or four |
| 5 days and more | Most of a week | Almost effortless |
Check your watches in the movement list. Long reserves are why the Tissot Powermatic 80 and Hamilton H-10 are so easy to live with.
Letting some stop is fine
A stopped watch comes to no harm, so there's no need to keep everything running. A winder is optional. Just set the date carefully when you pick it up again, and avoid 9pm to 3am.
Let an app keep the list
The hard part of rotation is memory: which automatic has been off longest, and which hand-winder was last wound when. Watch Winder tracks the reserve of every watch, suggests which to wear next, lists the hand-winders to wind today, and reminds you before any watch stops.
FAQ
How many watches can you realistically rotate?
Three to five is comfortable for most people, with all of them running. Beyond that, most collectors keep a few running and let the rest stop until they're worn.
How often should I wear each watch?
There's no mechanical need to wear a watch regularly. Wear what you enjoy; if one sits unworn for months, running it for a day every so often is a nice habit but not essential.
Should I keep all my automatic watches running?
Only if you want to. It's convenient for watches with complications that are fiddly to reset, but it doesn't make a movement last longer.
Which watch should I wear next?
Wear the running automatic with the least power reserve left. It gets topped up while the others still have time on their reserve.
Do I need a watch winder for a collection?
No. A rotation by power reserve keeps three or four long-reserve automatics running without one. Winders are most useful for perpetual calendars and moonphases.
